Examples

flow_info <- data.frame(from = LETTERS[c(1,2,3,3,4,5,6)],
                        to = LETTERS[c(5,5,5,6,7,6,7)])

dd <- data.frame(
    label = LETTERS[1:7],
    v1 = abs(rnorm(7)),
    v2 = abs(rnorm(7)),
    v3 = abs(rnorm(7))
)

g = igraph::graph_from_data_frame(flow_info)

p <- ggplot(g)  + geom_edge()
library(ggplot2)
library(scatterpie)

p %<+% dd + 
    geom_scatterpie(cols = c("v1", "v2", "v3")) +
    geom_text(aes(label=label), nudge_y = .2) + 
    coord_fixed()
